JOHN SCHADE, OE HOLYOKE, MASSACHUSETTS, ASSTGNOE To NATIONAL BLANK BOOKCOMPANY, OF HOLYOKE, MASSACHUSETTS, A VOLUNTARY ASSOCIATION or coPARTNERSHIP, HAVING AS TRUSTEES AND F. W. WILSON. l

Application led June 11,

T0 all whom it may concern.

Be it known that I, JOHN SCHADE, a citizen of the United States, and aresident of Holyoke, Hampden Count-y, Massachusetts, have inventedcertain new and useful Improvements in Loose-Leaf Books; and I dodeclare the following to be a. full, cle-ar, and exact description ofthe invention such as will enable others skilled in the ant to whichit'appertains to make and use the same.

This invention relates to loose leaf books, but more particularly hasreference to a book of this description in which the side covers areseparate elements that are secured in position to the back portion ofthe book.

The main objects of the invention are tov present a structure which hasall theadvantages in appearance of aone piece structure in which latterthe back and side covers are made/from an integral piece of leather orother suitable flexible material, a further object being to greatlyeconomize in the construction of the book, it being a comparativelyexpensive matter, involving waste in` a good many instances, to cut theSide covers and bac-k from a single piece of suitable material. Furtherobjects will appear from the following description taken in connectionwith the accompanying drawings in which Y Figure 1 is a perspective viewillustrating the side covers and back portion of myimproved book inproper assembled condition- Figure 2 is a cross section of the structureshown at Figure 1 with the cover plate in position- Figure 3 a br'okenperspective view of the metal back plate- Figure 4 is a plan View of thebackplate as it appears with one form of covering- Figure 5 is a. brokenperspective of the back plate showing another manner of covering theends, back and side edges thereof- Fi re 6 is a view similar to Figure 2but showing the covers secured in position byl gluing to the upperfacesbf the back'plate, and firmly held by the lower edges of the coverplate- Figure 7 is a.V broken perspective illustrating t-he coverl plateemployed in the construction shown at Figure 8+ Figure 8 is a viewsimilar to Figure 2 F.

showing a modified way of securing the covers to the back plate- Figure9 is ay view similar to Figure 6 showing particularly one way ofsecuring the cover for the bac-k plate, and the side covers, in thecompleted article, andl Figure 10 is a view similar to Figure 2, butshowing the spurs of the back plate upstanding.

Similar numerals of reference denote like parts in the several figuresof the drawing.

Before entering upon any description of this invention, it will be wellto state that the object of providing a cover for the outside surface ofthe metal back plate, is to afford the appearance of a structure inwhich the covers and back of the book are of one integral piece offlexible material, and from the description, hereinafter to be made, itwill be clear-that this cover may be secured in position in severalways. or may be entirely omitted, asmay be desired, the object of itsinclusion being merely to show the possibilities of the structure withno intention whatever of limiting the invention.

Referring to Figures 1, 2, and 3, of the drawing, 1 is a metal backplate having lanced therefrom spurs 2; 3 is a. cover for the outsidesurface of this plate, the side edges of this cover being turned overthe side edges of the plate 1 and secured thereto by gluing.

4 are the slde covers the book which are made of leather or othersuitable material having their inner edges skived and reduced inthickness as Shown at 5, which inner edges are impaled upon the spurs 2at the opposite side edges of the metal back plate and these spurs arethen preferably turned down against these skived portions 5, as shown atFigure 2. If' necessary, these portions 5 may also be glued to the"metal back plate, and also glued to the turned` vover edges of the cover3 these matters bev ing mere details.

The cover plate'G, which carries the ring f.

structure, is secured inv position with its lower edges firmly boundagainst the skived portions 5 of the side covers, by means of by a.special envelope of suitable material, as indicated at 8Y in Figure 4,and the spurs 2 would project through this envelope, and it will beobserved that the lat-ter is provided with end flaps 9, so that in thecoinpleted book no part of the plate 1 will be exposed. The sides of thecovering envelope, such as is shown in Figure 4, may not eX- tend to thecentral portion of the 'plate l, as illustrated at 10 in Figure 5; y

While it is'preferred to provide the spurs 2 the latter are,nevertheless, not absolutely necessary, since the skived portions at theinner side edges of the covers may be glued directly to the inner faceof the plate 1, and their permanency in this position insured by theclamping action of the lower edges of the cover plate 6, as is shown atFigure 6. Also, the side edges of the plate 1 may be turned over to formoverhanging portions l1 that are spaced from the inner surface oI' theplate, and the skived portions. of the covers may extend-over theseflangeduportions within this space, and be securely held in position bymeans of the lower edges of the cover plates 6, as shown at Figure 8,these lower edges being toothed or serrated as shown at,12 in Figure 7,so that they will embed themselves somewhat within the skived' portions5. 1`

Should it be necesary to provide the co `struction shown at Figure 8with a cover for the back plate 1, a suitable cover 13 can be glued tothe back 'of the plate and its side edges folded over the side edges ofthe plate and then glueal down upon the overhanging portions 11 betweenthe latter and the skived portions 5, as shown at Figure 9.

It is preferred that the spurs 2 be, clinched down againstA the upperfaces of the skived portions 5, as shown at Figures 1 and 2, but

this clinching is not necessary, since these skived portions can beglued directly to the inner face of the back plate, with the spurspiercing the same and upstanding, as shown at Figure 10, the cover plate6, when clamped in position, binding at its lower edges against theseskived portions, and by reference to v Figure 10, it will be observedthat these upstanding spurs in no wise interfere with the action of thering operating devices that are contained within this plate 6.

It will thus be noted that a loose leaf book with flexible covers has.been provided in which all the advantages of a; one piece structure areapparent, and it will further be observed that vt-he skiving at theinner edge portions of the covers will enable the latter to lbe openedand closed with gre-at facility.

`Wl1at is claimed is 1. A loose leaf structure, comprising a metal backplate, separate covers having their inner edges skived, and means forsecuring said coversy at their skived portions to the side edges of saidplate.

2. A loose leaf structure, comprising a metal back plate, a suit-ablecovering for the outer faces thereof, spurs lanced from the upper faceof said plate, and sepanarte covers having their inner edges skived andsecured at' these skived portions to the back platev by said spurs. l

3. A loose leaf structure, comprising a metal back plate, a suitablecovering for the outer faces thereof, clinching members inl tegral withsaid plate, and separate covers having their inner edges reduced inthickness and secured alt these reduced portions to the back plate bysaid members.

4. A loose leaf structure, comprising a metal back plate, separatecovers having the outer faces of their inner edge portions an unbrokencontinuation of the outer side faces of the covers, said inner edgeportions being reduced in thickness, and means integral with the metalback plate for clinching said portions at the side edges of said plate.

In testimony whereof I ailiX my signature hereto.

JOHN SCHADE.
